Specifications
The EL panel is a matrix structure with column and row electrodes arranged in
an X-Y formation. Light is emitted when an AC voltage of sufficient amplitude
is applied at a row-column intersection. The display operation is based on the
symmetric, line-at-a-time data addressing scheme.
Power
This display requires both 12V and 5V in addition to video signals for proper
operation. The display is designed to accept simultaneous application of V
L
, V
H
,
and the input logic signals. If these signals are not simultaneous, they must
meet the sequential timing shown in Figure 1 below.
Figure 1. Data/Power Connector
The supply voltages are shown in Table 1. All internal high voltages are
generated from the display supply voltage (VH). The logic supply voltage (VL)
should be present whenever video input signals or VH is applied. The
minimum and maximum specifications in this manual should be met, without
exception, to ensure the long-term reliability of the display.
Performance characteristics are guaranteed when measured at 25
q
C with rated
input voltage unless otherwise specified. Planar does not recommend
operation of the display outside these specifications.
